I think you will not have any problem with Typ C or Typ F.
Typ F is even more compatible as it fits the outlets with grounding. Typ C will not fit those outlets.

Kristianstads Handboll are a really good team:
Sveriges häftigaste handbollsklubb | IFK Kristianstad Skåne
Third place in the ranking at the moment.
I visited a friend in Malmö near Lund some weeks ago when I was in Sweden with my son visiting my father. That friend is deep into Innebandy (floorball)
http://floorballtoday.com/wp-content/uploads/2016/10/pixbo-aik.jpg and is really angry at the handboll-players because they use glue on the hands for better grip. That glue of course sticks to the ground when the ball is bounced. The floorball team has to scrap/clean the floor several times a year to be able to play.
